Bradley ABSTRACT: Material such as feed is transported by a conveyor and selectively delivered to either of two receiving stations by a diverter which is shiftable between a pair of delivery positions. Structure for discharging the material from the conveyor into the diverter moves with the latter as the diverter is advanced back and forth along the conveyor between spaced limits of travel by a drive therefor. Limit switches may be selectively conditioned by the operator for activation in response to the arrival of the moving diverter and cooperate with a releasable coupling between the structure and the diverter to enable the drive to shift the diverter from one delivery position to another as the diverter reverses its direction of travel.

FEED CONVEYOR In feed lots the use of conveyors toresupply feed bunks greatly reduces the manpower requirements for operation. However, in order to efficiently resupply a bunk that is common to several pens or lots, it is desired that some means be provided to selectively divert the feed from the conveyor into either side of the bunk, depending on feeding requirements. Furthermore, it is oftentimes desired to restock only a particular longitudinal section of the bunk that may, for example, feed a given pen, in which case discharge of feed from the conveyor must be limited to only that particular section of the bunk, in contrast to delivery of feed uniformly along the entire length thereof.

It is, therefore, the primary objectof this invention to provide material handling apparatus capable of selectively delivering material to either of two receiving stations as the material is discharged from a conveyor in a pass traversing the path of travel of the conveyor.

As a corollary to the foregoing object, it is an important aim of the instant invention to provide apparatus as aforesaid which is selectively operable to limit the length of the material-dischargingpass to effect delivery'of material to only a predetennined section; ofthe selected receiving station, in order that the apparatus may be employed to deliver the material to either the entire station or a preselected section or sections thereof in accordance with operational requirements.

Another important object of the invention is to provide such an apparatus in which a'selective diverter is employed for material delivery and wherein the drive for the diverter also automatically causes the same to change from one delivery position to another at the command of the operator.

Furthermore, it is an important object of this invention to provide-apparatus as aforesaid which is simple in design and relatively economical to manufacture, maintain and operate, and which is especially suited to feedlot operations but equally well adaptedto other material-handling applications requiring the selective delivery of material from a conveyor discharged in successive passes.

FIGS. 1 lare diagrammatic views illustrating the operawith an upstanding divider 34 which extends longitudinally thereof. Thus, the bunk 32 is divided into a pair of laterally spaced feeding stations or troughs 36 and 38, the latter trough 38 being illustrated as directly beneath the conveyor belt 20.

The standards 30 support a pair. of spaced, elongated horizontal rails 40 and 42, the latter being illustrated as box members extending along respective sidewalls 26 and 28. The rails 40 and 42 support a frame 44 comprising a pair of side members 46 and 48, a pair of crossmembers 50, and a pair of spaced rods 52 extending in'parallelism with conveyor belt 20 and interconnecting the cross members 50. A pair of support legs 54 depend from the inner rod 52 and the side member 46 and carry a scraper blade 56 which is disposed at approximately a right angle with respect tolconveyor belt 20 and in overlying engagement therewith.

Each of the crossmembers 50 is formed with a pair of opposed, depending, outwardly projecting feet 58 having antifriction pads 60 thereon resting upon respective rails 40 and 42, as is clear in FIGS. 2 and 3. A diverter broadly denoted 62 is shifiable carried by the rods 52 and comprises a pair of delivery sections having oppositely facing inclines or slides 64 and 66. The diverter 62 is compartmentalized by a center partition 68 between a pair of end walls 70 and 72 to form the two sections, the slide 64 being disposed betweencenter partition 68 and end wall 70 with the slide 66 thus disposed between the center partition 68 and the end wall 72. A pair of eyes 74 are secured to the upper edges of each of the end walls 70 and 72 and receive respective rods 52 for sliding movement of the diverter 62 therealong. A bracket 76 projects laterally from the diverter 62 for the purpose of providing a connection for a pull line in the form of a drive cable 78 spaced above the rail 42.

A plate 80 is secured to the end of one of the crossmembers 50 adjacent sidewall 28 for the purpose of mounting a pair of vertically spaced retaining straps 82 which embrace an elongated, upright latch 84. With particular reference to FIGS. 6 and 7, it may be seen that the latch 84 resembles a clothespin in appearance and has a longitudinal slot 86 therein communicating with its lower end, thereby presenting a pair of spaced legs 88. The upper end of the slot 86 is reduced in width and communicates with a pair of opposed recesses 90, each configured to complementally receive either of a pair or buttonlike stops 92 attached to the cable 78. Thestops 92 are cylindrical in configuration and thus are readily guided by the outer, frustoconical portions of the recesses into the cylindrical internal bore portions thereof, communicating with slot 86, as may be seen most clearly in FIG. 7. A ramp 94 (FIGS. 1 and 4) is secured to the inner surface of sidewall 28 above the rail 42 and is engageable with the lower end of the latch 84 during movement of the diverter 62 and the scraper 56 for control purposes to be discussed hereinafter. As will be subsequently explained with respect to FIG.- 10, three ramps 94, 94a and 94b are employed at different locations along the path of travel of the scraper frame 44.

As may be seen in FIGS. 1 and 3, a pair of magnetic reed switches S3 and S4 are mounted on the inner surface of sidewall 26 above the rail 40, a pair of permanent magnets 96 FIG. 16 is an electrical schematic diagram of a simplified,

exemplary control circuit for the apparatus.

Referringto FIGS. 1-7, a belt conveyor is fragmentarily shown having an endless belt 20 trained around a roller 22 being'carried by the side member 46 of frame 44. The limit switches S3 and S4 serve as sensors and are horizontally spaced from each other a distance equal to the spacing between the two permanent magnets 96. These limit switches and magnets are also employed in the control of the apparatus and, asv illustrated diagrammatically in FIG. 10, additional magnetic reed limit switches S1, S2, S5 and S6 are provided.

Referring to the alternative form of the invention illustrated in FIGS. 8 and 9, a tray-type conveyor 98 is shown having a shiftable tray support 100 disposed in underlying relationship to individual trays 102 of the lower stretch of conveyor 98. Each of the trays 102 has a pivotal axis 104 adjacent one end thereof, the opposite end of the tray being normally disposed in overlying relationship to the proximal end of an adjacent tray 102. Thus, the trays I02 mutually support one another unless the support 100 is removed to dump the contents of the beneath the conveyor belt 20, the bunk; 32 being provided 75 trays 102 in domino fashion.

The diverter 162 in the alternative embodiment is similar to the diverter of FIGS. 1-7, and has a pair of generally oppositely facing, inclined slides 164 and 166. The diverter 162 is pulled by a drive cable 178 having a pair of spaced stops 192 thereon, as in the previous embodiment. The latch 184 and associated parts are identical to that as shown in FIGS. 6 and 7, and the diverter 162 is slidable upon a pair of rods.l52 carried by a frame 144. Since the shiftable support 100 is employed to control the discharge of material from the trays 102, the support 100 is mounted on the frame 144, the latter having crossmembers 150 provided with feet 158 which ride on rails 140 and 142 in the same manner as described above with respect to the first embodiment.

Referring to the exemplary control circuitry illustrated in FIG. 16, the various limit switches S1-S6 are shown schematically as normally open, single-pole switches. A diverter position switch 200 has three-ganged poles 202, 204 and 206 that are connected to the return side or negative terminal of a DC power source 208, as illustrated by the ground notation. A

latch relay 210 is employed and comprises a pair of coils 212 and 214 on a common armature operating a pair of single-pole relay switches 216 and 218. A reversible DC motor 220 is connected to the poles of the two switches 216 and 218, the output shaft thereof being diagrammatically illustrated as coupled with a drive pulley 222 having the cable 78 trained therearound. A pair of single-pole, double-throw limit selecting switches 224 and 226 are provided, together with a singlepole, double-throw switch 228 associated with limit switches 85 and S6 for a purpose to be discussed hereinafter.

OPERATION .are illustrated diagrammatically in FIG. 10 and shown in FIGS. 1 and 3. The description of operation will commence with the frame 44 and diverter 62 located at their left limit of movement, which would be a location above the left end of the bunk 32. This is depicted in FIG. 11 where the downwardly directed arrow represents the discharge of feed by scraper 56 from the belt onto the slide 64.

In FIG. 11, the diverter 62 and the frame 44 (carrying scraper 56) have just completed a pass over the length of the bunk 32, during which-time feed was continuously discharged into the trough 36. This occurred since the upper stretch of conveyor belt 20 moves to the right and had previously transported a supply of feed from the hopper end of the conveyor into overlying relationship to bunk 32, such feed being scraped from belt 20 as the scraper blade 56 advanced to the left along the length of the conveyor. (The hopper end of the conveyor is the left end thereof which is not shown in the FIGS.) It is now, therefore, necessary to reverse the direction of movement of diverter 62 and frame 44 to commence rightward movement thereof back toward the right end of the bunk 32.

This occurs automatically since the diverter position switch 200, for delivery from slide 64, has its poles 200-206 in engagement with the right-hand contacts thereof. Thus, only limit switch 81 may be activated to closed position by the presence of the first magnet 96 coming into close proximity thereto. (Limit switch activation is illustrated in the diagramm'atic views of FIGS. 11-15 by the solid block representations.) When S1 closes, relay coil 212 is energized by a circuit through the upper contact of limit selecting switch 224, the

latter being the left limit selector and illustrated in a position which selects limit switches S1 or S2 as defining the left limit of movement of the frame 44 and diverter 62. If the pole of switch 224 were in engagement with the lower switch contact, either limit switches S5 or S6 would define the left limit. Similarly, selector switch 226 selects the right-hand limit of movement and is shown in a position selecting either limit switch S5 or S6 as the right-hand limit. The switch 228 is employed to prevent the possibility of inadvertently selecting the same limit switch (either S5 or $6) for both left and right limits.

When S1 closes to effect energization of relay coil 212, the poles of relay switches 216 and 218 shift into engagement with their left-hand contacts to reverse the polarity of the connections to motor 220. This reverses the direction of movement of cable 78, the latter being a continuous cable trained around a drive pulley 222 (illustrated in FIG. 16) and an idler pulley which is not shown. Prior to reversing the direction of movement of the cable 78, the left stop 92 was retained by latch 84 to provide a coupling between frame 44 and diverter 62 during leftward movement thereof. However, with reversal of the direction of movement of the cable 78, the left stop 92 separates from the latch 84 a short distance limited by engagement of the right I end of diverter 62 with the right crossmember 50 of frame 44. Thus, as is clear in FIG. 11, the two units 44 and 62 will now move to the right in unison.

At the right limit, the lead magnet 96 moves into close proximity to limit switch S3, whereupon the latter closes to energize relay coil 214 by a circuit through the limit selecting switch 226. It should be understood that relay coil 212 was previously deenergized as switch S1 reopened upon movement of the units away from the left limit, but the relay switches 216 and 218 remained latched against their left contacts. Therefore, energization of relay coil 214 shifts the relay switches 216 and 218 to their right-hand contacts to reverse the connections to the motor 220. When this occurs, the cable 78 begins movement to the left and reengages the left stop 92 within the latch 84 as the right-end of the diverter 62 and the right frame crossmember 50 separate a short distance. The units now move back to the lefi so that scraper 56 will again discharge feed from the conveyor belt 20, the latter having advanced to the right with the units with a fresh load of feed.

The lost motion at each limit as the diverter 62 changes its direction of movement is necessary at the left limit in order to disengage the left stop 92 from the latch 84. Referring to FIG.

7, it may be seen that the stop 92 must be withdrawn from the corresponding recess 90 in order for the latch 84 to shift upwardly clear of the stops 92 when the bottom end of the latch 84 engages one of the ramps 94, 94a or 9412. The importance of this is illustrated in FIG. 13, where the initiation of a change in the position of diverter 62 is depicted. In FIG. 13 it is assumed that the operator now desires to load feed into the other trough 38 and, for this purpose, the feed must be discharged onto the slide 66. Thus, the operator actuates the diverter position selector switch 200 to return the poles 202- -206 thereof to the positions illustrated in FIG. 16. Now movement of the units is under the control of limit switches S2 and S4; therefore, when the unitsapproach the new right limit as in FIG. 13, movement continues until the leadmagnet 96 moves into close proximity to switch S4. At this time the latch 84 has moved onto ramp 94 to raise the latch 84 clear of the cable 78, i.e., the cable 78 now extends between the legs 88 in the portion of the slot 86 of maximum width. Therefore, the stops 92 can now pass freely between the legs 88 of the latch 84 as the cable 78 begins leftward movement upon energization of relay coil 214 by the closure of limit switch S4. This uncouples the two units until the left end of the diverter 62 moves into engagement with the left frame crossmember 50 as shown in F IG. 14. The point of discharge of the feed from the conveyor is now aligned with the slide 66.

FIG. 15 depicts the operation of the apparatus at the new left limit established by the limit switch S2. When switch S2 closes in response to the presence of the lead magnet 96, relay coil 212 is energizedtoshift the relay contacts and reverse the drive as discussed above with respect to the closure of switch coupling between the two units for rightward movement thereof in unison. If it is subsequently desired to again position the diverter 62 for delivery from its slide'64, this is accomplished at the left limit by simply operating the position selector switch 200 to condition S1 for activation and remove S2 from the circuitry. The units would then continue leftward travel until the lead magnet 96 moves into close proximity to switch S1, whereupon the drive would reverse and the units would assume the positions shown in FIG. 11 where the drive coupling for rightward movement is' an abutment between diverter 62 and the. rightframe member 50. This is accomplished since the latch 64 is now permitted .to ride up upon the ramp 940 as the units terminate their leftward movement, during which time the right-hand stop 92-. is disengaged from the latch 84 as in FIG. 14. Thus, the latch84 is free to shift upwardly clear of the stops 92, permitting the same to pass between the legs 88 thereof as the cable 78-shifts to the right.

With reference to. FIG. 10, it maybe appreciated that the latch 84 will pass over the intermediate ramp 94b as the two units 44 and 62 reciprocate betweenleftand right-hand limits established by switches S1 and S3 or S2and S4. It is significant to note, however, that the'latch will not release upon engagement with the ramp 94b because the respective stop 92 is captured'within the corresponding recess 90 and follows the movement of the latch 84. in order for 'thelatch 84 to release and clear the stops 92, the latter must be disengaged from the latch 84 as depicted, for exarnple,-in FIG. 13.

Assuming that it is desired to deliver feed to only a preselected stretch of the bunk 32, limitswitch S5 or S6 is utilized by appropriate positioning of the limit selecting switches 224 and 226. Manifestly, additional pairs of. limit switches and associated ramps may be interposed along the path of travel of the units 44 and 62 as may be desired to divide the bunk 32 into longitudinal sections that may be selectively fed.

Operation of the alternative form of the invention shown in FIGS. 8 and 9 is the same as discussed above with respect to reciprocation between desired limits and the selection of a particular diverter. slope l64-or 166 for feed delivery. The only difference is in the manner of discharging feed from the conveyor 98 into the diverter 162, such being effected by movement of the support 100 leftwardly beneath the trays 102. The lower stretch of the conveyor 98 moves to the right and the trays 102 are filled at the left endthereof (not shown), the lead tray 102 being held in a horizontal attitude by the support- 100 as the latter follows the lead tray 102 during rightward advancement thereof. when the support 100 reaches the desired right-hand'limit, the drive for the diverter 162 and the frame 144 carrying support 100 reverses to cause the trays 102 to sequentially-move to their dumping positions over the selected section of the diverter 162. This occurs in domino fashion as the two units advance to the left, whereupon the trays 102 refill after the left limit is reached and the drive reverses to again shift frame 144. and diverter 162 back to the right.
